Abstract:

A simple and atom-economic synthesis of highly substituted thiophenes is demonstrated. Heating a solution of a chalcone and a linear/cyclic 1,3-dicarbonyl compound with elemental sulfur in CH3CN in the presence of NEt3 at 80 °C afforded the corresponding substituted thiophenes in good to excellent yields.

Abstract:

AbstractThe decarboxylative coupling of diversely substituted benzoic acids with internal alkynes proceeds smoothly in the presence of a [RhCl(cod)]2/1,2,3,4-tetraphenyl-1,3-cyclopentadiene catalyst system to selectively produce highly substituted naphthalene derivatives. The catalyst system is applicable to constructing anthracene and benzo[c]thiophene frameworks through reactions of naphthoic and thiophene-2-carboxylic acids, respectively.

Abstract:

We describe the design and synthesis of ferrocene dimers and trimers bridged by an oligothiophene spacer as both cathodic and anodic multiple redox-active organic–organometallic hybrid molecules. The electrochemical properties of all compounds were examined by cyclic voltammetry (CV). The voltammograms showed different multi-step, multi-electron redox reactions derived from multi-ferrocene fragments and the organic spacer. The results indicate that a number of thiophene rings in the spacer can be attuned to the redox potentials and the electron-transfer processes.

Abstract:

The behavior of a modified porous silicon surface (PSi) with polythiophene (PTh) for para-nitrophenol (p-NPh) detection by cyclic voltammetry was studied. Nitrophenols are organic compounds which are the most used in the production of pesticides but also in the dyes and pharmaceuticals. In particular, p-NPh is a toxic derivative of the parathion insecticide and is considered as major toxic polluant because it is soluble and stable in water so it can affect soil. Porous silicon was prepared by electrochemical etching and it was modified by an oxide layer. PTh films were grown on this surface us

Abstract:

Cyclic 2-amidofuranones were obtained from the Rh(II)-catalyzed reaction of alpha-diazoketo substituted pyrrolidine derivatives. These compounds are derived by a [1,4]-hydrogen transfer from an initially formed carbonyl ylide dipole. Acylation of the amido-substituted furanone with pivalyl chloride provided a fused amidofuran, which underwent bimolecular Diels-Alder cycloaddition with N-phenylmaleimide. The Rh(II)-catalyzed decomposition of ethyl 2-diazo-3-oxo-(2-oxo-1-pent-4-enoyl-pyrrolidine-3-yl)propionate was also examined. In this case, the alkenyl group tethered to the amido carbonyl und

Experimental conditions were developed under which these reductions could be done selectively, giving good yields of the desired products. Electroreduction of tetrabromothiophene can also lead to the formation of a poly-bromodithienyl mercury compound.

Abstract:

Substituted nitrogen heterocycles are structural key units in many important pharmaceuticals. A new synthetic approach towards heterocyclic compounds displaying antibacterial activity against Staphylococcus aureus or cytotoxic activity has been developed. The selective synthesis of a series of 64 new N-heterocycles from the three nitrobutadienes 2-nitroperchloro-1,3-butadiene, 4-bromotetrachloro-2-nitro-1,3-butadiene and (Z)-1,1,4-trichloro-2,4-dinitrobuta-1,3-diene proved feasible. Their reactions with N-, O- and S-nucleophiles provide rapid access to push-pull substituted benzoxazolines, ben

Abstract:

A cyclopropanone, a cyclopropenone, cyclobutanones, a cyclobutane-1,3-dione, and a cyclobutene-1,2-dione reacted with dimethoxycarbene to afford acetals of the next larger ring by formal insertion of the carbene into a CC bond α to the carbonyl group. When either of two saturated α-ring carbons could be involved in the process, the ring expansion was selective, affording primarily the product of apparent insertion into the more substituted ring bond. With 2,3-dimethoxycyclobutene-1,2-dione, insertion occurred between the carbonyl groups and with β-propiolactone it occurred at the lactone bond
